3. Punisher Joins The Avengers
With each new Avengers movie comes the need for exciting new recruits. Who would be a better surprise than the man himself Frank Castle? There's no way Punisher would become an Avenger we hear you say. Well cast your minds back to Ultimate Comics: Avengers 2 when Frank is finally captured by Captain America and given the chance to avoid execution if he agrees to join the Avengers at the request of Nick Fury. Although Castle's allegiance with Earth's Mightiest Heroes was only short lived it doesn't change the fact that believe it or not Frank Castle was a card carrying member of the Avengers for a brief period of time. It wouldn't be a stretch to bring Punisher into the fold if he sees a mutually beneficial resolution at the end of it. He'd of course be a loose canon that the others couldn't trust but a brief stint as one of Nick Fury's chosen few would be an easy way to reboot his character into the current Marvel Universe.
